Specification forming part of Letters"Patent N0. 222,263, dated December 2, 1879 application tiled May 5, 1879.

hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of th-is specilication, in which- Figure l is a longitudinal vertical section of an oil-can, showing oui-improvements applied thereto. Fig. 2 is a front elevation of the saine; n and Fig. 3 is a. 'detail perspective, show.-v ing the mannerof forming the ditch or recess in the side of the can to receive the gagetube.

Our invention has for its 'object to provide means for permitting visual inspection of the extent or quantity of the iiuid contents of cans and other like vessels; and our improvements relate to the provision in a metallic vesf sel ot' a gage made of glass or equivalent transparent material, the vessel being con-V structed to receive the gage within its perimeter, and said gage being fastened by means of cemcntor equivalent, as hereinafter fully set forth.'

Referring to the accompanying drawings, A. indicates a can or equivalent vessel, such as is or may be used for the holding and transportation of oil, varnish, spirits, mi1k,'&c.

Two lateral incisions are made near the top and bottom edges of the can, as shown at a a,

l and two vertical incisions, a' al, the metal between said lateralincjsions, indicated by the letter B in Fig. 3, being depressed or pushed ,inwardly to form a concave uiche,B, in the side of the can, said niche being open at top' and bottom, as shown at bb, the metal above sa-id niche, bounded on two sides by the incisions c a', being lapped, as at a2, Fig. 3.

C represents a glass tube, or tube of equivalent transparent material, located in said niche B', being inserted in position by passing it endwise through the openings b b. When, so

located said tube is lfastenedin position and rendered tight to avoid leakage by cement applied at d d. Such cement should be of such UNITED STATESPATENT- OFFICE."

character that itwill be impervious to the' action of the fluids which the can is designed to hold.

For milk-cans the cement ordinarily employed in households for domestic purposes, 0.,the sealing of fruit-jars, &c., will suiiCe; but for petroleum and its products,such article will not answer, and in such case we use a peculiar cement, the composition o`t` which wereserve as subject-matter for another application for. patent. p

not absolutely necessary. The exterior` wall of the vessel adjacent to the niche B and tube C is provided with a scale,y E, shown in Fig. 2. to indicate pints, quarts, gallons, or fractional parts thereof.

By preference, the filling-neck, shown at F, is directly over the tube (l, so that the latter may be cleaned by a brush', Gr, passed 'down through the latter, as shown plainly in Fig.'1.

lhe quantity of fluid contents of the vessel will be ascertained by an inspection of the gage E, and hence no measure will be required to be used in iilling. The provision .of vthe gage will also enable purchasers to see that they get full measure, a fact outside of mere visual inspection in ordinary metallic vessels unprovided with gages, where the sufciency of the amount supplied by a vendor can be ascertained only by pouring out and remeasurin g the contents of a vessel.
